Skateboards have definitely come a long way since Marty McFly ripped the crate from a kid’s home made scooter and grabbed onto a passing car to escape Biff in 1955. In recent times we’ve seen the humble skateboard evolve through the addition of a motor in such vehicles as the Tami Rhino and Wheelman BUSHPIG. The most recent example to join the ranks is the MXB Shocker Motocrossboard from Performance Concepts – an electric-powered cross between a snowboard and a dirtbike that has an average range of 18 miles, recharges in two hours and – with some tweaking – can hit 35 mph.
